New Jersey Gov. Chris Christie chose an unusual method for explaining his recent decision to hold a special Senate election in October: Slow-jamming the news on “Late Night with Jimmy Fallon.”

The fun-loving Republican participated in the slow-jam session Wednesday night on the “Fallon” show — proving to be a good sport who played along even when the slow-jam lyrics turned at least partially blue.

“Aw, yeah,” rapped Jimmy Fallon as he traded lines with Gov. Christie. “Chris Christie is about to give New Jersey a huge election,” Fallon crooned, in one of the slow-jam’s more “colorful” passages. “And he’s puttin’ it in the hands of the people!” Fallon continued. “So watch out, because it’s comin’ prematurely — Oct. 16 to be exact.”

In setting up the special election, the governor acted in accordance with the New Jersey state Constitution, which gives him the power to call a special election for a vacant U.S. Senate seat when a senator resigns or dies while still in office. That’s what happened when Sen. Frank Lautenberg, a democrat, died earlier this month at age 89.

Christie first appointed an interim senator — New Jersey attorney general Jeff Chiesa — who will serve only until the special general election in October. Christie has been criticized by some for setting the special election in October, just a few weeks away from next fall’s traditional Election Day on the first Tuesday in November.

When the governor sat down with Fallon for an interview, Fallon thanked him for slow-jamming, and the governor responded by declaring he’s better at it than NBC News anchor Brian Williams, who’s Fallon’s customary partner in these slow-jam segments.

The two then talked about Christie’s efforts to lose weight, including the lap-band surgery he underwent. And, as a late-night comedian who has relied heavily on jokes about Christie’s weight, Fallon asked: “What’s going to happen to my monologue if you do this?”

The governor also talked about the perks associated with being a national celebrity — including meeting Bruce Springsteen, whom Christie has long idolized, and Bono of U2. The story about Bono was particularly exotic.
